Some suggestions for working with the meditation decks:
Either 
by selecting a card at random, or looking through an entire deck, with 
each image, notice the feeling(s) it evokes and where in the body it's 
felt.  What does a particular image say to you?  You may want to journal
 whatever comes up.  
Pause during your day to spend time 
looking through your deck as a way to refocus.  Slow your breath and 
allow your body to relax as you hold your deck and take in each image.   
Using
 the deck as a lead-in to meditation can be a powerful exercise.  Draw 
an image from your deck.  Pause to really experience the photo.  Take in
 the colors, shapes, images.  Close your eyes and attempt to recall the 
image in detail as you focus inward.  
Display the deck on an 
easel somewhere in your home or office where you will view it often.  
Rotate the images as often as you are called.
